要从 StringCollection 的指定索引处移除，代码如下 −
示例
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
StringCollection stringCol = new StringCollection();
String[] arr = new String[] { "100", "200", "300", "400", "500" };
Console.WriteLine("Array elements...");
foreach (string res in arr) {
Console.WriteLine(res);
}
stringCol.AddRange(arr);
Console.WriteLine("Total number of elements = "+stringCol.Count);
stringCol.RemoveAt(3);
Console.WriteLine("Total number of elements now = "+stringCol.Count);
}
}
输出
这将产生以下输出 −
Array elements... 100 200 300 400 500 Total number of elements = 5 Total number of elements now = 4
示例
让我们看另一个例子 −
using System;
using System.Collections.Specialized;
public class Demo {
public static void Main() {
StringCollection stringCol = new StringCollection();
String[] arr = new String[] { "A", "B", "C", "D", "E" };
Console.WriteLine("Array elements...");
foreach (string res in arr) {
Console.WriteLine(res);
}
stringCol.AddRange(arr);
Console.WriteLine("Total number of elements = "+stringCol.Count);
stringCol.RemoveAt(1);
stringCol.RemoveAt(2);
Console.WriteLine("Total number of elements now = "+stringCol.Count);
}
}
输出
这将产生以下输出 −
Array elements... A B C D E Total number of elements = 5 Total number of elements now = 3
